That would depend on what you call "good for editing", and what kind of editing/3D work you are doing.
If you are doing very simple 720p (maybe lower-bitrate 1080p) editing, then you may be fine, however any high quality 1080p and higher resolution will 100% make it choke, or even complex 720p work.
With Blender, it also depends on what you are doing. If you are making very simple models with a low polygon count, then you may be fine, but anything higher than that or any animation, and this will scream to a halt instantly.
I personally wouldn't have bought a computer with a 12 year old dual-core i5 with integrated graphics for the purpose of editing and 3D work. You could upgrade it to 16GB of RAM and an SSD, which will definitely help with the machine feeling fast overall, however the low-spec 12 year old hardware will most likely be a choke point.
